Revised Air Emission Standards For Portland Cement Manufacturing Industry

EPA has finalized proposed amendments to the National Emission Standards for Hazardous Air Pollutants (NESHAP) for the Portland Cement Manufacturing Industry and the Standards of Performance for Portland Cement Plants. These amendments were proposed on July 18, 2012.
This final rule amends the national emission standards for hazardous air pollutants for the Portland cement industry. In addition, the EPA  amended the new source performance standard (NSPS) for particulate matter.

The final rule is effective on February 12, 2013. The EPA set the compliance date for existing open clinker storage piles to be February 12, 2014 and set the date for compliance with the existing source NESHAP to be September 9, 2015

EPA amended the existing and new source PM standards in the NESHAP and changed the numeric emissions value of those standards. The agency changed the alternative organic HAP (oHAP) standard , but did not change the existing or new source standards for mercury, THC or HCl.
